Nuclear, water and fossil fuel are the primary sources of our electricity. Nuclear power is a clean and efficient source of energy. It emits almost no carbon dioxide which contributes to global warming. It can generate lots of amounts of energy. The designs of a nuclear are readily available today and no researching is necessary which will add to building cost. New designs make it safer than the old generations which were used in Chernobyl and Three Mile Island, but of course still, there is no such thing as a fail safe device. If a nuclear plant fails, it consequences could be catastrophic. The waste which it produces is also still a problem, and the danger is that it is the only power plant that produces radioactive wastes. The wastes are somewhat similar to industrial toxic wastes but more deadly and in the event of a plant failure, can cause a catastrophe for it can poison the landscape not just for years but even centuries. The wastes produced can also be used for the production of nuclear weapons.

Hydro electric power is probably the most widely used form of renewable energy source. It is clean and produces almost no carbon dioxide emission. It uses the potential energy of water from a high elevation that drives water turbines and generators. Hydro electric power plants are a cheap source of energy because not only is it renewable but it is also not affected by the rising cost of fuel or coal. However, using hydro electric also has its raw backs. To construct a hydro electric plant, a very large reservoir is needed and consequently submerging a very wide area upstream of the dam. This will in turn destroy ecological systems not only upstream of the dam but also downstream of it.

Fossil fuel power plants are the most widely used source of energy today. Most countries use this kind of energy source because of its large scale power production and continuous supply it provides. Although it provides large amounts of power, it also produces a lot of greenhouse gases and is considered as one of the major contributors to global warming. There are efforts to reduce the emissions of fossil fuel power plants but experts say that it will not be available commercially and on a large scale basis until 2025.

Wind power is probably the most economical of all sources of energy. The power of the wind can be utilized by using a wind turbine or what is popularly known as the windmill. They can convert wind power into mechanical energy, which can be used to grind grains or pump water; and electric power with the use of generators. It can be said that it is like an electric fan working in reverse, instead of electricity making the blades rotate to produce wind, the wind rotates the blades to produce electricity. Large wind turbines can be grouped together in a wind farm to produce large quantities of electricity for public use. There are also small scale wind turbines that can be used at home. They are very clean, renewable and can dramatically reduce electric bills.
